Okay, in RB, you can't adjust tempo while the song is playing (are you trying to do accelerandos or decelerandos?). But I know in 2012 (and I believe in 2011.5 - don't know aobut 2011), you can change the tempo of the whole song by setting a new tempo.

If you want to do what Trax suggested, you'll have to re-generate Realtracks after setting the new tempo, as just inserting a change at a point will only adjust the MIDI tracks, not the audio tracks (at least in my quick testing, it didn't).
